好吧,我有這樣的代碼,裁剪圖像,並顯示它,我想要做的是,而不是僅僅顯示它,我想將圖像保存在此文件夾中是完整的代碼如何把圖像放入目錄imagejpeg()?

$source_path = $_FILES['Image1']['tmp_name'];

list($source_width, $source_height, $source_type) = getimagesize($source_path);
switch ($source_type) {

imagecopy(

imagejpeg($desired_gdim);

?>
我的問題是在最後一行,其中imagejpeg($desired_gdim);
應該imagejpeg($desired_gdim, 'img/whatever-filename.jpg');
但圖像沒有在瀏覽器甚至表示,它不會被髮送到該目錄,另外,如果我想與我已使用相同的上傳它的文件名中插入它事情發生只是一個破碎的圖像的小圖標
header(content-type:image/jpeg),你想要顯示圖片,只需使用'imagejpeg($ desired_gdim $ filename)' – 2013-03-11 08:01:14
定義「不工作」。發生了什麼或沒有發生什麼?你有任何錯誤?你檢查過了嗎? – deceze 2013-03-11 08:01:18
刪除標題(內容類型),它用於渲染不保存。 Regards – 2013-03-11 08:02:04
